swapping the mapView

Hi Guys

I have a mapview displaying region A. On pressing a button, I want to swap to region B. MY code on click is

mapSwitchButton.addEventListener('click', function(e)
{
    Titanium.API.info("You clicked the button");

    if(mapSwitchButton.title == 'show area 1') 
    {
        mapSwitchButton.title = 'show Pick-Up';
        mapView.region = { latitude:43.623075, longitude:-79.480988, 
                        latitudeDelta:0.002109, longitudeDelta:0.005284 };
        mapView.setAnnotations(mapAnnotation1);
    }
    else 
    {
        mapSwitchButton.title = 'show area 2';
        mapView.region = { latitude:43.828923,  longitude:-80.52927, 
                         latitudeDelta:0.01548, longitudeDelta:0.042272 };
        mapView.setAnnotations(mapAnnotation2);
    }
});

this doesn't work - it causes the application to restart. I would appreciate it if someone could give me a pointer to how I swap regions

Regards, Richard

mapView is defined in the same function as the button

the error I see is
